</p>
<p>For an explanation of the concept of 1D 测量 see the introduction of

In addition
the edges are grouped to pairs: If <a href="#Transition"><i><code><span data-if="hdevelop" style="display:inline">Transition</span><span data-if="c" style="display:none">Transition</span><span data-if="cpp" style="display:none">Transition</span><span data-if="com" style="display:none">Transition</span><span data-if="dotnet" style="display:none">transition</span><span data-if="python" style="display:none">transition</span></code></i></a> = <i><span data-if="hdevelop" style="display:inline">'positive'</span><span data-if="c" style="display:none">"positive"</span><span data-if="cpp" style="display:none">"positive"</span><span data-if="com" style="display:none">"positive"</span><span data-if="dotnet" style="display:none">"positive"</span><span data-if="python" style="display:none">"positive"</span></i>,
the edge points with a dark-to-light transition in the direction of the major
axis of the rectangle are returned in <a href="#RowEdgeFirst"><i><code><span data-if="hdevelop" style="display:inline">RowEdgeFirst</span><span data-if="c" style="display:none">RowEdgeFirst</span><span data-if="cpp" style="display:none">RowEdgeFirst</span><span data-if="com" style="display:none">RowEdgeFirst</span><span data-if="dotnet" style="display:none">rowEdgeFirst</span><span data-if="python" style="display:none">row_edge_first</span></code></i></a> and

In this case, the corresponding edges with a
light-to-dark transition are returned in <a href="#RowEdgeSecond"><i><code><span data-if="hdevelop" style="display:inline">RowEdgeSecond</span><span data-if="c" style="display:none">RowEdgeSecond</span><span data-if="cpp" style="display:none">RowEdgeSecond</span><span data-if="com" style="display:none">RowEdgeSecond</span><span data-if="dotnet" style="display:none">rowEdgeSecond</span><span data-if="python" style="display:none">row_edge_second</span></code></i></a> and

behavior is exactly opposite.  If <a href="#Transition"><i><code><span data-if="hdevelop" style="display:inline">Transition</span><span data-if="c" style="display:none">Transition</span><span data-if="cpp" style="display:none">Transition</span><span data-if="com" style="display:none">Transition</span><span data-if="dotnet" style="display:none">transition</span><span data-if="python" style="display:none">transition</span></code></i></a> = <i><span data-if="hdevelop" style="display:inline">'all'</span><span data-if="c" style="display:none">"all"</span><span data-if="cpp" style="display:none">"all"</span><span data-if="com" style="display:none">"all"</span><span data-if="dotnet" style="display:none">"all"</span><span data-if="python" style="display:none">"all"</span></i>, the
first detected edge defines the transition for <a href="#RowEdgeFirst"><i><code><span data-if="hdevelop" style="display:inline">RowEdgeFirst</span><span data-if="c" style="display:none">RowEdgeFirst</span><span data-if="cpp" style="display:none">RowEdgeFirst</span><span data-if="com" style="display:none">RowEdgeFirst</span><span data-if="dotnet" style="display:none">rowEdgeFirst</span><span data-if="python" style="display:none">row_edge_first</span></code></i></a> and

I.e., dependent on the positioning of the measure
object, edge pairs with a light-dark-light transition or edge pairs with a
dark-light-dark transition are returned. This is suited, e.g., to measure
objects with different brightness relative to the background.
</p>
<p>If more than one consecutive edge with
the same transition is found, the first one is used as a pair element.  This
behavior may cause problems in applications in which the threshold
<a href="#Threshold"><i><code><span data-if="hdevelop" style="display:inline">Threshold</span><span data-if="c" style="display:none">Threshold</span><span data-if="cpp" style="display:none">Threshold</span><span data-if="com" style="display:none">Threshold</span><span data-if="dotnet" style="display:none">threshold</span><span data-if="python" style="display:none">threshold</span></code></i></a> cannot be selected high enough to suppress consecutive
edges of the same transition.  For these applications, a second pairing mode
exists that only selects the respective strongest edges of a sequence of
consecutive rising and falling edges.  This mode is selected by appending
<i><span data-if="hdevelop" style="display:inline">'_strongest'</span><span data-if="c" style="display:none">"_strongest"</span><span data-if="cpp" style="display:none">"_strongest"</span><span data-if="com" style="display:none">"_strongest"</span><span data-if="dotnet" style="display:none">"_strongest"</span><span data-if="python" style="display:none">"_strongest"</span></i> to any of the above modes for <a href="#Transition"><i><code><span data-if="hdevelop" style="display:inline">Transition</span><span data-if="c" style="display:none">Transition</span><span data-if="cpp" style="display:none">Transition</span><span data-if="com" style="display:none">Transition</span><span data-if="dotnet" style="display:none">transition</span><span data-if="python" style="display:none">transition</span></code></i></a>,

Finally, it is possible to select which
edge pairs are returned.

edge pairs are returned.  If it is set to <i><span data-if="hdevelop" style="display:inline">'first'</span><span data-if="c" style="display:none">"first"</span><span data-if="cpp" style="display:none">"first"</span><span data-if="com" style="display:none">"first"</span><span data-if="dotnet" style="display:none">"first"</span><span data-if="python" style="display:none">"first"</span></i>, only the first of
the extracted edge pairs is returned, while it is set to <i><span data-if="hdevelop" style="display:inline">'last'</span><span data-if="c" style="display:none">"last"</span><span data-if="cpp" style="display:none">"last"</span><span data-if="com" style="display:none">"last"</span><span data-if="dotnet" style="display:none">"last"</span><span data-if="python" style="display:none">"last"</span></i>,
only the last one is returned.
</p>
<p>The extracted edges are returned as single points which lie on the
major axis of the rectangle.  The corresponding edge amplitudes are
returned in <a href="#AmplitudeFirst"><i><code><span data-if="hdevelop" style="display:inline">AmplitudeFirst</span><span data-if="c" style="display:none">AmplitudeFirst</span><span data-if="cpp" style="display:none">AmplitudeFirst</span><span data-if="com" style="display:none">AmplitudeFirst</span><span data-if="dotnet" style="display:none">amplitudeFirst</span><span data-if="python" style="display:none">amplitude_first</span></code></i></a> and <a href="#AmplitudeSecond"><i><code><span data-if="hdevelop" style="display:inline">AmplitudeSecond</span><span data-if="c" style="display:none">AmplitudeSecond</span><span data-if="cpp" style="display:none">AmplitudeSecond</span><span data-if="com" style="display:none">AmplitudeSecond</span><span data-if="dotnet" style="display:none">amplitudeSecond</span><span data-if="python" style="display:none">amplitude_second</span></code></i></a>.
In addition, the distance between each edge pair is returned in
<a href="#IntraDistance"><i><code><span data-if="hdevelop" style="display:inline">IntraDistance</span><span data-if="c" style="display:none">IntraDistance</span><span data-if="cpp" style="display:none">IntraDistance</span><span data-if="com" style="display:none">IntraDistance</span><span data-if="dotnet" style="display:none">intraDistance</span><span data-if="python" style="display:none">intra_distance</span></code></i></a> and the distance between consecutive edge
pairs is returned in <a href="#InterDistance"><i><code><span data-if="hdevelop" style="display:inline">InterDistance</span><span data-if="c" style="display:none">InterDistance</span><span data-if="cpp" style="display:none">InterDistance</span><span data-if="com" style="display:none">InterDistance</span><span data-if="dotnet" style="display:none">interDistance</span><span data-if="python" style="display:none">inter_distance</span></code></i></a>.  Here, IntraDistance[i]
corresponds to the distance between EdgeFirst[i] and EdgeSecond[i],
while InterDistance[i] corresponds to the distance between
EdgeSecond[i] and EdgeFirst[i+1], i.e., the tuple
<a href="#InterDistance"><i><code><span data-if="hdevelop" style="display:inline">InterDistance</span><span data-if="c" style="display:none">InterDistance</span><span data-if="cpp" style="display:none">InterDistance</span><span data-if="com" style="display:none">InterDistance</span><span data-if="dotnet" style="display:none">interDistance</span><span data-if="python" style="display:none">inter_distance</span></code></i></a> contains one element less than the tuples
of the edge pairs.</p>

assumptions that the edges are straight and perpendicular to the
major axis of the rectangle are fulfilled.  Thus, it should not be
used to extract edges from curved objects, for example.
Furthermore, the user should ensure that the rectangle is as close
to perpendicular as possible to the edges in the image. Additionally,
